IMPROVEMENT IN STEAM VACUUM-PUMPS.

Specification forming part of Letters Patent No. 135,201, dated January28, 1973.

To all whom it may concern:

Be it known that 1, WILLIAM BURDON, of Brooklyn, in the county of Kingsand State of New York, have invented a Combination of a Steam-Engine, aSteam Vacuum-Pump, and a Water-Wheel, of which the following is aspecification:

This invention consists in a steam-engine, a steam vacuum-pump, and awater-wheel, when so combined that the exhaust steam from thesteam-engine is used to operate the pumps, and the latter supplies waterto the wheel to drive it, whereby the exhaust steam of the engine isutilized, and by means of the aforesaid pump and wheel, made to form anauxiliary to the engine, and a very economical and effective motivepower is produced.

In the accompanying drawing, Figure 1 is a view looking endwise at theengine and sidewise at the pumps and water-wheel, and Fig. 2 is aviewtaken at right angles to the former.

Similar letters of reference indicate corresponding parts in bothfigures.

A is the steam-engine, which is or may be of any known form. Its poweris communicated by a belt B, and suitable pulleys, to a counter-shaft,Another belt, D, connects this counter-shaft O with the valve-operatin gshaft G of the pumps E E, which are arranged some distance above theengine, on an upper floor "of a building, for instance. They are thesame as described in an application previously filed by me for LettersPatent, consisting of a series of vacuum-vessels whose steaminlet-valves are shifted by tap pets on the shaft Gr, before mentioned,to admit steam to them one after the other in regular succession, sothat one of the pumps is always in full operation, and a steady streamis constantly kept up. Steam is conducted to them from the engine A by apipe, 1?, which extends along the topof the whole series.

The water to be pumped is situated in thelower floor of the building,and is conveyed to the pumps throughapipe, O, which, like the steampipeP, just mentioned, extends alongthe whole series. All these pumpsdischarge into curbs or discharge-boxes, with which they are provided,and these all deliver into an adjacent trough, I, from which the wateris conveyed to the water-wheel J by a single pipe, K.

The water-wheel represented is one of the class known as turbines. Thewater enters its case or shell at one side, and is discharged throughthe bottom. The shaft of this wheel is geared by miter-wheels L L with acounter-shaft, M, from which power is communicated by a belt, N, to thecounter-shaft U, to which the power of the engine is also communicated,as I previously mentioned.

Steam is conducted in the ordinary manner I from a steam-generator tothe engine A, and when exhausted from the latter is conveyed to thepumps E E. By being condensed in the pumps one after another, it causeswater to be forced up into them, and then, by bein g afterward admitted,it destroys the vacuums and permits the pumps to discharge successively.The water delivered from the pumps is conducted to the wheel J, and byoperating it forms an auxiliary to the engine.

It is evident that if I utilize exhaust steam of an engine to theproduction of additional power, I have a clear gain, because I utilizethat which ordinarily is considered of no account. I therefore producean extremely economical and efiective motive power, which can be madefor a considerably less sum than almost any now in use.

My only reason for arranging the pumps in an elevated position is that Imay obtain a good head of water for driving the water- Wheel.

The same water may be pumped up over and over again where desirable.

What I claim as my invention is- A steam-engine, a steam vacuum-pump,anda water-wheel so combined that the exhaust steam from the engine isused to operate the pump, and the latter is made to supply thewater-wheel with water, whereby the exhaust steam is converted into anauxiliary to the engine, substantially as and for the purpose herein setforth.

WM. BURDON.
